Every year, Mardi Gras celebrations in New Orleans involve throwing thousands of beads into the crowds. While colorful and fun, these beads are more than just party favors—they can also be a source of microplastic pollution that harms our oceans and marine life. Curious about how this happens and what can be done? Below, we explore the environmental impact of Mardi Gras beads, what science says about microplastics, and how you can help reduce this pollution.
-
How do Mardi Gras beads contribute to microplastic pollution?
Traditional Mardi Gras beads are made from plastic, which can break down into tiny microplastics over time. When these beads are discarded or washed into storm drains, they often end up in lakes and oceans, where they persist for years. This microplastic pollution can be ingested by marine animals, harming ecosystems and entering the food chain.

What do scientific studies say about microplastics in oceans?
Research shows that microplastics are now widespread in oceans worldwide. Studies, including those focused on Lake Pontchartrain, reveal that microplastics originate from various sources, including plastic beads from celebrations like Mardi Gras. These tiny particles are found in water, sediment, and marine organisms, raising concerns about their long-term environmental impact.
-
Are microplastics harmful to humans and marine animals?
Yes, microplastics pose risks to both marine life and humans. Marine animals can mistake microplastics for food, leading to injury or death. For humans, microplastics can enter the food chain through seafood consumption, potentially causing health issues. Ongoing scientific research aims to better understand these risks and develop solutions.
-
How can consumers help reduce microplastic pollution from beads?
Consumers can make a difference by choosing eco-friendly alternatives, such as biodegradable beads made from natural materials like okra seeds. Supporting initiatives that ban or limit plastic beads and advocating for sustainable celebrations can also help reduce microplastic waste entering our waterways.
-
What are some eco-friendly options for Mardi Gras beads?
Many krewes and organizations are now offering biodegradable beads developed at LSU, which contain natural materials like okra seeds that can be planted after use. These eco-friendly options help reduce plastic waste and microplastics, making Mardi Gras celebrations more sustainable and environmentally friendly.
-
What efforts are underway to study microplastics in Lake Pontchartrain?
Scientists and organizations like the Pontchartrain Conservancy are actively researching microplastics in Lake Pontchartrain. They are assessing how plastic beads and other debris impact marine ecosystems and exploring ways to mitigate pollution. These efforts are crucial for developing effective policies and community actions to protect local waters.
